Breeding the T-bar Cichlid – Cryptoheros sajica

Sajica eggsCryptoheros sajica, formerly known as Archocentrus sajica, hails from Central America and belongs in the same family as the popular Convict Cichlid. I first came across this particular species of fish at an auction in Cleveland, where I picked up a bag for about five bucks. In the bag were 8 fish, each about a half inch in length.  At the time I was living in Cleveland, and they all went into a 30 gallon tank. They shared the tank with a 5 inch royal pleco and some neon tetras and rummynoses. I kept the water chemistry stable with a ph of around 7.6 and a general hardness of 6 degrees. The temperature was set at 78 degrees (F). The tank was furnished with live plants, driftwood and clay flower pots. I also added some flat stones, in hopes the new additions would eventually spawn on them.

They grew pretty quickly.  I fed them twice a day, and feeding was very easy. They pretty much ate anything that fell in front of their face. Every other day I performed water changes of about ten percent to keep the chemistry up to par.  By the end of the first year they were each about 3 inches long.

Finally, one day I had noticed that two had paired off.  They had all the others pinned in corners and fearing for their lives, so the following day I baged up the dominated fish, and traded them in for some baby brine and earthworm flakes before they met an untimely death by the newly territorial and greedy pair. Within days I noticed the couple cleaning one of the flat stones. I also noticed that the female’s breeding tube was visible, a sign that eggs are soon to come. She laid about 100 small. tan-colored eggs the following day. It happened to be my day off, and I was excited that she had laid her first batch of eggs, Little did I know that the pleco decided he had an appetite for caviar. The inexperienced soon-to-be parents tried to keep the intruder away, but the pleco was determined to have his fancy meal. The damage done, I relocated the pleco to my African cichlid tank.

Sajica eggsShe had another batch of eggs 3 weeks later. This time they were better prepared, and with no armored, sucker-mouthed egg eaters in their tank, they were on the road to success. These fish are very good parents once they get the hang of it! They guarded their offspring ferociously, even attacking the gravel tube as I tried to clean the substrate. When they were big enough, I moved the fry I could catch to a seperate 20 high. About 50 fry made it to be traded and sold from that batch.

I don’t consider sajicas a very vibrant species, though they are attractive in their own way. They remind me a lot of the A. spilurus, with their shimmering blue eyes. Maybe their most striking feature is the blue throat developed by both males and females as they mature. Males attain an adult size of 5 inches and females about 3.5 to 4 inches. With caution they may be kept with community fish, but they are almost always aggressive towards others of their own kind. I would say the minimum tank size for an adult pair would be a 29 gallon. I would highly recommend this species to someone who would like to try something other than a Convict Cichlid. They breed easily and are really fun to watch as they spawn and raise their fry. If you have any questions about them, please let me know in the comments section!

Done With Dovii, On to the Next Cichlid Breeding Venture – Cuban Cichlids

Jose’s Male DoviiSo since my last blog, my male Wolf Cichlid has done it again. Another disasterous fit of rage or passion, but this time though he decided to kill his mate. The female that produced more than a couple thousand babies in the short three years that she was mine is dead. I wish I knew what was going through his fishy mind, because he was as brutal as OJ during his jealous tirade (ooops, just kidding, we all know OJ is innocent). Like OJ, my mean male has managed to avoid capital punishment, banished to a holding tank at TFP before he can be re-homed to some other lucky (or unlucky) cichlid enthusiast.

So, now I have to figure what I should try to breed next! Several things came to mind immediately; Grammodes I’ve already bred, Argentia I’ve kept but never bred, and then there were the  the Cuban Cichlids (Nandopsis tetracanthus). These medium-sized, powerhouse fish attain lenghts of up to 14 inches. They are very striking fish, both male and female are monochromatic, that is, they both sport a black and white pattern.

I was able to trade my rotten male dovii on 4 1.5 inch fish. They all went into the 40 breeder and have so far adapted really well, they were already eating an hour after being put into their new home. The following day I did a head count and was glad to see all four fish still kicking, as everything I’ve read says they are highly aggressive towards each other. Let me tell you it is so true!
They have set up the pecking order already, though they haven’t inflicted too much damage on each other yet. To break up the tension in the tank, I also introduced a Chromidotilapia sp. individual from West Africa. The little Cubans quickly went over to check out the new fish, but the dominant male was smart not to attack, since it was 2.5 times
his size. By the looks of things (if I go by size) I may have two pairs!

They feed very well. The dominant male will pig out so much his belly distends, almost to the point that I have to be careful to limit his intake…he sometimes looks as if he’s about to explode. My bet is that he will grow very quickly. These guys take everything from flakes to sinking pellets, as they get larger I will also feed them nightcrawlers and red worms. I wish that Dovii hadn’t killed his mate…he is a beautiful boy, but I couldn’t stand to look at hm after that carnage. It happens when you keep these crazy fish. So I’m hoping to have my first batch of Cuban Cichlid eggs in about 6 months from now…until then wish me luck!

Look forward to updating you on the situation!

Rift Lake Cichlids for Small Aquariums – Breeding Shell-dwelling Cichlids


I’d like to welcome Jose Mendes to That Fish Blog. Jose is our resident Cichlid Pro. In addition to working at TFP for 13 years, he’s been breeding Cichlids for over 14 years and has produced over 200 different species. Check out Jose’s article below on setting up a Nano-cichlid habitat.

10 Gallon Rift Lake Cichlid Habitat

Working at That Fish Place/That Pet Place, I get a lot of questions regarding what type of African cichlids can be kept in small aquariums – particularly 10 gallon aquariums. Here I will try to answer some of the common questions concerning basic requirements and species specifics.

When a customer asks which cichlids are ok for a 10 gallon tank, I tell them to keep shell dwellers. These fish are from Lake Tanganyika and the majority of them only reach an adult size of 2 to 3 inches in length, though some do grow larger.

Let’s start with the tank itself. A regular 10 gallon glass tank is fine. For substrate, I prefer sand like Carib Sea Aragamax which I mix with Carib Sea Tahitian Moon black sand. The reason for choosing Aragamax is that not only does it help maintain the pH level in the aquarium, but it allows the fish to act naturally and bury their shells. My setup at home consists of a small cave in one corner and the remaining area is sand; into which I add 2 snail shells for each fish. For fish up to 2 inches I like shells the size of a quarter. (Medium turbo or apple shells work nicely.)

A 50 watt aquarium heater will be just fine. The temperature should be set between 78 and 80 degrees.

Filtration for this tank should be an outside power filter that turns the tank volume over 8 to 10 times an hour. Under gravel filters should be avoided!

The water chemistry in the lake is very hard with a pH of around 9.2. I’ve found from breeding shell dwellers that a pH of 8.4 or higher and a general hardness of at least 10 dkh is best for them.

Before I detail a few of the species, I’d like to share a few things I’ve learned from keeping and breeding these fish:

Weekly water changes: I’ve always done them and always will. 10% is enough to make a difference in health, vigor, and spawns.

Water conditions in my breeding tanks were all the same and were as follows: pH 8.6, General hardness 15+, and temperature 81 degrees.

For feeding; do not feed worms! Bloodworms, black worms, or tubifex. These will kill African cichlids sooner or later. Appropriate food would be any prepared small cichlid flake. They prefer sinking foods, but not necessarily pellets.

Have patience. Breeding shell dwellers is easy. Start out with a group of 5-6 individuals of one species. Don’t move the shells around and don’t add new fish. The fish will reward you for your diligence.

Now let’s detail some of the species that I would recommend for a 10 gallon aquarium. Once again do not mix more than one species per tank.

Lamprologus kungweensis: Adults reach lengths of 2.5 inches with females being slightly smaller than males. An identifiable trait of this species is the golden/yellow mark above each eye that becomes more apparent as they mature. Sexing is not easy there is not much dimorphism. Besides being smaller, the female is lighter in color and less intensely marked.

Neolamprologus Ocellatus GoldLamprologus ocellatus: A stunning 2 inch fish whose name means “eyespot” due to the distinctive spot, outlined in gold, on the fish’s operculum. In addition to the gill cover, the ocellatus has a gold colored iris, a golden cream colored body and clear fins speckled with blue or gold. Sexing is fairly easy; the male’s dorsal fin is edged in an orange/red band while the female’s is clearly paler and often edged in white. Also, mature females are rounded while males are more oblong in shape. The most distinctive feature of a pair is the size difference. Males are almost ½ inch larger than females and the teeth appear larger and more prominent. One of my favorite shell dwellers on the market is the Golden Ocellatus, which has a golden sheen to the whole body.

Lamprologus ornatipinnis: As the name implies, the appeal of this species lies in its ornate fins which are distinctively marked with a series of striations that vary in color from purple to black. While a mature male may reach a total length of 2 inches, the females are ½ inch smaller. The female is also considerably plumper with a metallic purple sheen developing over the abdomen as she comes into breeding condition.

Lamprologus signatus: Another small but striking shellie, males top off at 2 inches, females slightly smaller. L. signatus are more elongate or torpedo shaped than other Lamprologus species. These display clear sexual dimorphism. The flanks of the males are crossed by dark vertical bands that extend through the dorsal to anal fins. The females are drab with only a slight pink hue to their abdomen.

Neolamprologus boulengeri
Neolamprologus brevis: At less than 2 ¼ inches N. brevis is a shiny beige color with up to nine silvery-white bands. Iridescent pastel blue striations mark the upper jaw, the cheek, and the anterior third of the body. Females are slightly smaller and show fewer extensions of the pectoral fins.

Neolamprologus boulengeri: Attaining a length of 2 ½ inches, N. boulengeri is an attractively marked shell dweller. In addition to the characteristic blotch pattern across the flanks, they have a yellow/orange margin in the dorsal and anal fins. The upper jaw sports a vivid metallic blue moustache which continues as a thin blue iridescent stripe across the operculum and flank.

Neolamprologus Meleagris
Lamprologus meleagris: The so called “lace lamp” or “pearly ocellatus”, L. meleagris is a diminutive silvery/black cichlid that rarely exceeds 2 ½ inches in total length. Its flanks are purplish with a series of irregular pearl like spots that highlight the scales and fins. The throat is silvery with hint of blue; the eye is set off by a bright blue streak behind the orbit. Females are smaller than males and their colors are not as intense, even when breeding.

Neolamprologus multifasciatus: The smallest of the shell dwelling cichlids of Lake Tanganyika. As the name implies, N. multifasciatus has a “many striped” pattern over its body. The edges of the caudal, anal, and dorsal fins are highlighted with bands of yellowish/orange and white. Sexing mature specimens is simple because though the female is marked the same as the male, she is fully grown at under 1 inch, while the male reaches 1 ¼ inch.

Neolamprologus similis: Similar in appearance to N. multifasciatus but with a larger eye and greenish/brown body color and contrasting light green markings. The bands extend further over the forehead of the fish. Adult size is nearly identical to N. multifasciatus as well.

In closing, I would have to say that shellies are the type of cichlid for people who want to keep cichlids but don’t have the room for a larger tank, (especially college students) and their natural breeding behavior is fun to watch. They are a lot of personality packed into a small fish!
